NYC Weekend Weather – Oct 4, 2019

Strong high pressure and sunny weather will be the main theme this weekend. Despite the sun, we do have a chance to see the coldest overnight temperatures so far this season tonight into Saturday. High temperatures start to warm from the 60s to the low-70s by the second half of the weekend and to start next week as the high pressure progresses east and we get warmer southerly return flow before the next storm system approaches Monday.

Rest of today – sunny with high temperatures in the mid-60s. Breezy with a refreshing northerly wind, 15-20 mph with higher gusts due to the relatively tight pressure gradient between the high pressure building moving in from the west and the low that brought us rain yesterday continuing to move offshore. Cold overnight, with lows in the upper-40s. Frost advisories and freeze warnings are up for many areas of upstate New York not too far from us.

850 mb winds as indicated by GFS model for 8AM today, indicating the presence of strong winds of 30-40 knots just above the surface.
As the day progresses, the near-surface layer up to 850 mb is forecast to become well-mixed, and this will allow the faster winds above to reach the surface.

Saturday – a sparkling, sunny fall day with high temperatures in the low-60s. Wins will calm also. Overnight lows in the mid-50s with increasing clouds.

Weather Prediction Center surface forecast for 8AM Sunday

Sunday – the cloud shield preceding an incoming storm system will continue moving in Sunday resulting in partly sunny skies. High temperatures will warm to around 70°F as winds turn to the south. This is due to the high pressure exiting east (clockwise flow around this) as well as winds ahead of an approaching cold front. Overnight lows in the low-60s.

Monday – mostly cloudy with chances for rain increasing later in the day. High temperatures in the mid-70s. Heavier rain accompanying the passage of a cold front overnight with lows dropping into the upper-50s.
